Pre-order a WP7 phone through AT&T, and you’ll pick up a month of Zune-Pass for free (as well as the game ilomilo). That’s $15 of unlimited streaming music, that they hope you’ll get hooked on, and keep buying. Of course, this is overshadowed by the fact that if you pre-order from Microsoft directly, they’ll hook you up with a three-month free pass, which is a much better deal.
Better yet is Austrian carrier A1, who are giving a free 4GB XBox 360 to everyone who picks up an HTC Trophy. Free 360s? Dang, why can’t they do that on this side of the pond? It’s a great way to push the XBox Live integration.
